Abstract
Abstract A reinforced insulated wall construction having a core of thermal insulation material which is reinforced by high-slenderness-ratio reinforced concrete columns. High compressive and side-load strengths are achieved by centrally supporting reinforcing members in vertical passageways in the core while the remainder of each passageway is filled with a concrete slurry and by so centrally supporting the members until the slurry hardens into concrete. Further side-load strength enhancement may be achieved by encasing at least a central length portion of each concrete column in a high flexural strength structural tubular casing.

Claim 1
Independent Claim
158 words
A reinforced insulated wall construction which is reinforced by high slenderness ratio reinforced concrete columns, said construction comprising a first sheet and a second sheet of facing material disposed in spaced relation, a core of thermal insulation material disposed intermediate said sheets, said core having a plurality of vertically extending, laterally spaced passageways provided therein, a tubular liner disposed in each said passageway, said liner having only about its central elevational one third length portion comprised of a relatively high flexural strength tubular form, an elongate, high-slenderness-ratio reinforcing member disposed in each said tubular liner, said reinforcing member having a relatively small transverse cross section relative to said tubular liner, means for axially positioning said member in said passageway throughout its length, said means for axially positioning said reinforcing member comprising a plurality of longitudinally spaced radially extending spacer elements, said reinforcing members and said spacer elements being encased by and said tubular liners being filled with concrete.
